After the molds are dipped and sanded 12-15 times, a final dip is done. The final dip does not include sanding. After the mold is dry after the final dip, the top of the cup and metal handle are cut off. The photo depicts molds that have been final dipped and the cut off has been completed. You can see the brown wax inside the mold. Note: the thickness of the mold. The mold has to be thick enough to survive the heat of the melted bronze.
The students are loading the molds into the burn out kiln. The molds are loaded into the kiln so the wax will pour out from the opening created after the cut off was completed. The molds are heated for at least two hours until they are completely clean of wax. The wax accumulates at the bottom of the kiln. We reuse the wax to make the cups discussed in a prior post.
